Feel free to add yourself here if you plan to work on the project. There will be some email-based discussion and record keeping for this project, and that info will be added here if you just want to lurk and complain.

Keypad hardware hooked up to Minotaur at /dev/ttyS3 - [https://www.noisebridge.net/pipermail/noisebridge-discuss/2012-February/028485.html The fucking dorkypad is finished]

/usr/local/share/baron/codes.txt - codes file, any line starting with a 4-7 digit number (ignoring whitespace) is interpreted as a valid code, # is used for comments

−

====Keycode Generation====

−

There can be any number of plugins that generate keycodes, they will be stored in a flat file on minotaur. Hipe is working with Kelly and Tom to build this.

−

−

==== Behavior ====

−

* Keypad accepts 4-7 digit codes.

−

* When a valid code is entered, the light turns green, a happy noise is played, and the gate is buzzed.

−

* When 7 digits are entered (that are not a valid code), the # or * keys are pressed, or 5 seconds passes after the last keystroke, the light turns red and a sad noise is played. (And the key buffer is reset.)

−

* If the gate API throws us an error, the light turns red and a sad noise is played three times.

−

* The list is checked at each keystroke, so if both 3345 and 334567 are valid codes, 334567 will never be usable — the gate will open immediately once a user types 3345. This was a design decision to make it faster/easier to enter a code, but it can be changed if desired. (Just remove "and digits not in codes" from baron.py, and you'll be able to use # and * to terminate a code less than 7 digits long.)

−

−

==== Todo ====

−

* Add an access log of some sort, and switch out stdout debug/error messages for something more useful

−

* Add a way to add/remove codes (from Pony?), somehow syncing the file to Minotaur.

−

* If you change the way codes are loaded, please ensure it's done in a way that won't interrupt a user in the middle of using the keypad. (So, don't just restart the process.) Currently, it tries to refresh the codes list in a background thread every 30 seconds — if the file is corrupted or missing, it continues with the last good list.

−

* Add a "bad" codes list, to block codes from being reused.

−

* Add the ability to expire codes - maybe a comment in the codes.txt file?

−

−

==Keycode System Features==

−

*Numberpad on front door

−

*Database of codes... on pony? With notes? Probably we need a basic schema for what info we do and don't want to log.

−

**Tom wants it to be a text file with a pin or rfid code per line and comments delimited by hash marks

Commercial door control systems usually have a central controller which is physically located inside the building and cannot be accessed from the entry box. The code entry box is connected to the controller via hard wires (usually serial). The controller can activate the doorlatch via the existing [[Getting In | Noisegate]] relay.

===Potential Products===

−

*Jake has volunteered to design and make serially-accessed codepads, one for the gate and one for inside.
